VMCI queue pair allocation is disabled, if a VM is in FT mode. In
these cases, VMware Tools may still once in a while attempt to
create a vSocket stream connection, resulting in multiple
warnings in the kernel logs. Therefore downgrade the error log to
a debug log.

Hi Jorgen, recently, our customer reported that their dmesg was also
swamped by the following message along with the message above.
"Could not attach to queue pair with -20"
This message was printed by vmci_transport_queue_pair_alloc(). Could
we also eliminate it?
Thanks,
Firo
